PICTURE-PROJECTING DEVICE.

Specification of Letters Patent.

Patented Application filed February 17. 1915. Serial No. 8,960.

To all whom it may concern.

Be it known that I, MAXLY M. GILLAM, a citizen of the l'nited States,residing at Flushing, Long Island, in .the county of Queens and State ofNew York, have in vented certain new and useful Improvements inPicture-Projecting Devices, of which the following is a specification.

My invention relates primarily to the class of picture projectingdevices which is designed to project or present the pictures or .imagesof'opaque objects, such as photographs, written or printed matter,engrai ings, woven fabrics, pottery, minerals, etc., on a screen orother suitable surface.

The object of" my invention is to give to devices of this class a wideradaptability. particularly for use in connection with retail trade, bydoing away with the necessity for a darkened room or'audience space inwhich the said image must be shown to be effective.

To this end I provide a casing, inclosure, or box-like form,sutliciently large to accommodate the picture projecting device at oneextremity and to form or receive a frame or support at the otherextremity of any size or shape desired to hold the translucent screen,curtain or other surface on which the projected picture or image is tobe shown. I prefer that the casing or boxlike form be of uniform heightand width throughout but it may be tapered to conform with therequirements of the light rays in transit from the projecting, device,or given any other desired form that will insure a properly darkenedinterior. Through the hollow interior of this casing, inclosure orbox-like form the reflected rays of light from the projecting devicepass on their way to the translucent screen, curtain or other displaysurface, and appear on its opposite side or front, in natural colors,illuminated and enlarged to any degree desired, the. dis

' nary daylight ofa room or of etc:

the modification at will of distinctly visible to observers in :8 makingthe device available for cl conspicuous andat ractire display orpresentation of written or printed announcements, advertising matter,photographic or other pictures and many other features of publicity orof popular interest, of great value in promoting the growth and progressof a business enterprise. By providina for the amount of projection tobegiven to the ditic sides of the shadow-box, or the anteriorlyprojec'ting marginal associated parts of the translucent display space,the eli'cctiveness of the illuminated.pictures or images may beconsiderably increased. because of the adjustment to peculiar lightconditions which is thereby made easily possible. Since the illuminateddisplay space is often above the level of the eyes of the observers itis-at times found that a very considerable anterior projection of theupper part oi the shadow box is an advantage.

in a retail store a favorite place for the location of the combineddevice is often on the top of a fixture behind a sales counter and withthe picture or image display surface near to and facing an aisle, orpassage way. or assembling lace for the use of the public. lint sincethe combined device is easily movable, if such construction is detitsirable. it may be placed lit-will wherever f its operation ispreferred. in any location on ascllingz floor of a store, if the sizeand shape of-the casing, inclosure'or box-like form permits, it is oftendesirable to utilizes, some of the space in its sides for the dis playor storage of merchandise or other objects. -To that end I considerablynarrow the open interior of that part of the said casing or box-iikeform nearest the said picture projecting device by means of longitudinalupright partitions, gradually tapered or stopped outward from the centerin the direction of the translucent screen or display surface, and infront of each recess thus formed 1 place a protective cover of glass orother material, if such protection is deemed necessary.

In some instances it is advisable that the body of the combined deviceshall not be located in the room in which the proposed pictures orimages are shown. Under such conditions the picture projecting devicemay be placed wherever convenient, and where the required degree ofdarkness can be se' cured, it only being necessary for the satisfactoryoperation of the combined device for business. amusement or educatioiialpur' poses that its picture or image displaying face be visible to thoseexpected to observe it.

A moving picture projecting device may be used instead of the device forprojecting the pictures or images of opaque objects if so desired, thesame general conditions applying to both. In either -case 1 provide,when necessary, in the immediate surroundings of the picture projectingdevice means for preventing dan er from tire. I also provide means forholding the devicc'in position and for adjusting it to the requireddistance from the display screen.

As a display screen material I prefer ground glass, lightly silveredglass or a very fine grade of tracing cloth. Through either of these thepicture or image of an object, either stationary or in motion, can beprojected with fidelity to the original and with satisfactory clearnessto those who observe the display face of the screen.

The nature and scope of my present invention will be more fullyunderstood from the following description taken in connection with theaccompanying drawings, forming part hereof, in which Figure l, is aperspective view of one formof the combined device, in anoperativeosition, with a part of one side removed.

ig. 2, is a view of a longitudinal cross section of the combined deviceparallel to its base. Fig. 3, is a perspective view of part of one sideof one form ofthe combined device showing a method for utilizing )art ofthe space in the casing, inclosure or oxlike form for the storage ordisplay of.

merchandise or other objects. Fig. -l, is a perspective view of theextremity of one mm of the combined device which contains thetranslucent curtain, screen or other surface on which the projectedpicture or image appears. Fig. 5, is a perspective view of one means forholding the picture projecting device lat any desired distance from thetranslucent screen or curtain.

Referringto the drawings, a, in Fig. 1, represents thebght raysproceeding from a'picture projecting device through an aperture in itscasing toward thetranshment 55 screen or curtain, a a, represents thecasing or inclosure of the picture projecting device with one sidepartly removed; this casing or inclos'ure may if desired be of metal, orof other material lined with as- 'which the picture projecting devicemay be moved either forward or backward while.

In Fig. 3; is shown a perspective of a longitudinal part otthe combineddevice, Fig. 1. with the side removed to show one method of utilizingthe display or storage space provided by partitions, a. on each side ofthe picture projecting device, tapered or stepped outward from thecenter in the direction of the translucent screen or curtain. 1/9. theshelf, (1 as indicated, being intended to give additional resting placefor the storage or display of articles.

In Figs is shown. a", a top and a side section of the shadow box, aconsiderably projecting beyond the outward face of the translucentscreen or curtain. (1?, it being understood that these as well as theother sides oi the said shadow box may be adjusted at will in a similarmanner, with either a greater or a less projection, with relation to thetranslucent screen, or curtain, u.'-'.'with which they are associated.

In Fig. 5, is shown one means, (1", for holding the picture projectingdevice in any desired position by the use of an eccentric which, atwill. may be made to engage or press against the track or guide, a, theeccentric being'molmted on the base of the frame supporting the pictureprojecting dw vice.
